1). c) 2). c) 3). c) 4). d) 5). c) 6). b) 7). c) 8). b) 9). d) 10). b)

Solution:
1).    Number of heads = B + D = 7                        …(i)
Number of legs = 2B + 4D = 20                              …(ii)
From statements (i) and (ii)
B = 4 and D = 3
2).

Required distance = 10 + 5 = 15 km
3). A + C= 70 yr
B + D = 80 yr
B + C + D = 120 yr
C = 40 yr and A = 30 yr
A + D = B + C
30 + D = B + 40
D – B = 10 yr
B = 35 yr and D = 45 yr
4). There is no ‘F’ letter in the keyword
Therefore, the word FIST cannot be formed
There is no ‘K’ letter in the keyword
Therefore, the word LARK cannot be formed
There is no ‘C’ or ‘Y’ letter in the keyword. Therefore, the word HYPOCRISY cannot be formed
Hence, PISTON word can be formed from the given word.
5). There is no’K’ letter in the keyword. Therefore, the word YOKE cannot be formed.
6). As, 5 × 6 + 3 × 3 = 39
And 7 × 5 + 4 × 4 = 51
Similarly, 5 × 5 + 3 × 4 = 37
7). As, 9 + 7 – 5 =11
And 6 + 4 – 8 = 2
8 + ? – 4 = 7
? = 11 – 8 = 3
8). As, 7 + 5 = 12,
12 + 10 = 22
And 22 + 15 = 37
Similarly, 3 + 5 = 8;
8 + 10 = 18
And 18 + 15  = 33
9). Let the number of keepers = x
Then, total number of legs = 2 × 50 + 4 × 45 + 4 × 8 + 2x
=2x + 100 + 180 + 32 = 2x + 312 [Hen = 2 legs, Goat = 4 legs, Camel = 4 legs and keeper = 2 legs]
And total number of heads = 50 + 45 + 8 + x = 103 + x
[Hen = Goat + Camel + Keeper = One head]
According to the question,
(2x + 312) = (103 + x) + 224
x = 327 – 312
x = 15
So, required number of keepers = x = 15
